First results from an ultra-fast frame image acquisition diagnostic coupled to a 2.45 GHz microwave hydrogen discharge are presented. The plasma reactor has been modified to include a transparent doubled shielded quartz window allowing to viewing the full plasma volume. Pictures describing the breakdown process at 1μs exposure time have been obtained for integrated visible light signal, Balmer-alpha, Balmer-beta lines, and Fulcher-band. Several different plasma emission distributions are reported. The distribution depends on the magnetic field configuration, incident microwave power, and neutral gas pressure.

Cortázar, O. D.; Megía-Macías, A.; Tarvainen, Olli; Kalvas, Taneli; Koivisto, Hannu (American Institute of Physics, 2015)

The relationship between Balmer-α and Fulcher-band emissions with extracted H + , H + 2 , and H + 3 ions is demonstrated for a 2.45 GHz microwave discharge. Ion mass spectra and optical measurements of Balmer-α ...
Influence of axial mirror ratios on the kinetic instability threshold in electron cyclotron resonance ion source plasma

Toivanen, V.; Bhaskar, B. S.; Koivisto, H.; Maunoury, L.; Tarvainen, O.; Thuillier, T. (American Institute of Physics, 2022)

Electron Cyclotron Resonance (ECR) ion source plasmas are prone to kinetic instabilities. The onset of the instabilities manifests as emission of microwaves, bursts of electrons expelled from the plasma volume, and the ...
